Transmitted to that person or not. We'll now have a and the dealing with four possible situations of a person or thing becoming impure, but we don't know for sure. The rule generally is: if there's a, if there's a doubt about something becoming in the, in the private domain, we treat the item as if it's... If that safek (a doubt) arose in the public domain, we say the opposite, that the item remained... In the four situations of the Mishnah, we'll talk about a doubt that arose in the private domain, but there's still a... The Mishnah says there are four cases of doubt in this Mishnah where Rabbi Yehoshua is going to rule that the item that we're talking about becomes... but say that it remains... What are these cases?
Number one, the person we're talking about someone with somebody with leprosy. That person was, he was standing under a roof in a private domain, and a pure person passed by close by in that private domain, but we don't know whether the... And the opposite, that the the person was standing under the roof in a private domain and the person the was passing by close by in the private domain. We don't know whether the... and the opposite, that the... Number three, the the item was in the private domain and that opened into a public domain and the item was in the public domain, but we don't know whether that came into the private domain and became or not from the item. Number four, the item was in the private domain and that opened up into the public domain and the item was in the public domain. We don't know whether the item entered the private domain and transmitted to the item.
So there are three possible ways that the could have been transmitted in each of these situations. Number one, there's a doubt whether or not the item touched the other; we don't know if they actually had physical contact. Number two, there's a doubt whether or not Tumah (impure) was transmitted by means of a roof. If they were under the same roof together, similar to Tumat Ohel (tent impurity), they would become the Tumah would be transmitted. And number three, there's a doubt whether one item moved the other.
So now we'll elaborate and we'll see the between where we say that in a private domain, so we apply the general rule about a doubtful case in a private domain and way to Tumah like we've said. But according to Chachamim (the Sages), they say that in that the rule doesn't apply in the first two cases with the metzora (someone with leprosy), because they say that that rule doesn't apply to the metzora. That's excluded from how we analyze things. The metzora is not included. And in the last two cases, when we don't know whether the item in the public domain ever entered the private domain, we say that this rule doesn't apply. The only time this rule, where we assume that a safek is metameh, that it becomes impure, according to the Chachamim, is if the item was definitely in the private domain, we just don't know if the Tumah transfer happened. But if we don't even know if the item was in the reshut hayachid (private domain) or not, then we don't apply this rule at all, according to the Chachamim.
